vfs_handle_struct->data usage

[Junji Kanemaru at LinuxML]

For the people who gave me the info, thanks!

The "data" member seemed designed that way but wanted
to make sure if it is used in some other purpose.

I looked into full_audit code and found I should start based on it.
It is highly configurable so. Thanks for pointing me to it.

By the way the output messages generated by full_audit look
like formatted in some manner that tokens are separated with
'|'(pipe). Is it designed for some parser that's already been
used somewhere?
I'd like to have output messages more readable form like:

smbd_audit: opendir("My Document"): result="success" user="nobody"
host=192.168.234.1 ...

You'd say it makes things slower and memory consumption
should be concerned though.

I'll post patch for full_audit for people review when it's done.

Thanks,
